Wolves ran out 1-0 winners at the London Stadium in the Premier League clash back in September, when Adama Traore’s 93rd minute goal proved the difference between the two sides.
But Moutinho, an experienced Portuguese international, knows the visitors have improved dramatically since their first meeting and will be up for revenge.
On away victory over West Ham
“I liked the victory. I don’t care if we win in the final minute of the match, it is not important. We won the last time we played against West Ham, but it is a different match. They are better now.
“After that game they played very well and will come here with great confidence, but we are confident about the game. We know all the games in the Premier League are difficult and we need to do everything to win.”
On West Ham’s key players
“In the game we played against them before they didn’t play too much like a team, but now they play like a team.
“Individually they have the players who can make the difference. They have a lot of players like Arnautovic and Anderson who are very good players.
“But it’s not only players in attack, it’s the players in the back, the midfielders; they have a lot of quality in the team and they will come here to try and win the game.
“But we are playing at Molineux with our supporters and we want to continue from the result against Leicester in the Premier League, before the FA Cup.
“After West Ham, we will want to continue to improve and be better every day, and every game.”
On Premier League form
“It is fantastic, but for me, it is better when we are calmer, but it is good because we are a team.
“We played very well the first half against Leicester. We scored two goals, maybe we could have done more but it doesn’t happen, and after six minutes it’s 2-2 and it is difficult for us, but we continued.
“To score in the last minute to make it 4-3 was very good for us, and it gives us a boost heading into the next match.
“But we need to be focused because it will be a very difficult match tomorrow.”
